Marathon Rubicon names the Pfhor home planet as Pfhor Prime. While this is not cannon, does anyone know if the a more correct labeling would have been "Pfhor Primus"; e.g. using the ordinal numbers instead? I suppose a rough translation would be "Pfhor the First" for primus and "Pfhor One" for prime. I don't know enough about latin, or proper use of ordinal numbers, to call it either way.

Sorry if this is the wrong board for this question, but that would be incredibly typical of me anyway.

Although there's no reference that I can find to "Pfhor Prime" in any of the official Marathon terminals or documentation, in Infinity Tycho makes reference to "Gr'ndl Prime" which is presumably a Pfhor-occupied planet used as a conditioning base of some kind. The use of Prime there seems to lay out the linguistic groundwork for interpreting Pfhor planet names, so I'd go with it as written.

Also, this is fiction, so they can write whatever the shit they want and it's "correct" anyway.
